LAMP-BRACKET.

SPECIFICATION forming part of Letters Patent No. 319,1e6, dated June 2,1885. Application filed June 23, 1884. (No model.)

To all whom it may concern:

Be it known that I, ROBERT L. Sronns, a citizen of the United States,residing at Jeffcrsonvillc, in the county of Clarke and State ofIndiana, have invented certain new and useful Improvements in LampBrackets, of which the following is a specification, reference being hadtherein to the accompanying drawings.

The object of this invention is to increase the utility of the peculiarform of lamp-bracket seen in Letters Patent No. 275,434, granted to meApril 10,1883. In the present case I use the perforated L-shap ed plateseen in said patcut, but add to it a third limb, which latter is tappedto admit a thumb-screw,wherewith the bracket can be readilyand securelyclamped either to a horizontal or vertical support such, for example, asa table or shelf or a wmdow or door casing. Furthermore, this L- shapedplate is provided with a pair of diametrically-opposite sockets adaptedto admit the spindle of an ordinary swinging bracket, which sockets areused with the fixed pins or pintles seen in said Patent No. 275,484. Theaddition of the extra limb and the provision of the two sockets and thepair of fixed pintles or pins, together with a perforated flange, allowthe bracket to be used in a number of ditl'erent positions, of which theold bracket is incapable, as hereinafter more fully described.

In the annexed drawings, Figure l is a sectionized side elevationshowing my improved bracket clamped to a table or shelf. Fig. 2 is asectionized end elevation of the bracket. bracket fastened to a verticalsupport.

My improved bracket consists of a pair of members, A B, that perform thefunctions of the L-shaped plate seen in the patent previously alludedto, a third limb, 0, being added to the member 13, so as to constitutean open jaw of such a capacity as to grasp ordinary tables, shelves,850. The limb or member B is pierced at D D, to admit nails, screws, orother retaining devices when it is desired to secure the bracketpermanently in place.

An extension or prolongation, E, in line with the limb A has twosockets, G F, inter- 3 is an elevation showing the secting each other,as seen in Fig. 2, the socket G being horizontahwhile the other socket,F, is vertical. Connecting this extension E and the limbs B G is a webor flange, H, perforated at I I, a pin or pintle, J, being arranged toproject vertically from the limb A at its end most remote from saidextension. Furthermore, a second pin or pintle, K, projectshorizontallyfrom the bracket at or near thejunction of the limbs A B, which pintlescan be used in the same manner as the corresponding devices seen in myold patent.

Tapped into the end of limb C is a thumbscrew, L, carrying at topabutton,l\I,ada-pted to bear against the support to which the bracket isclamped. In Fig. l the bracket is shown clampedto the edge of a table orshelf, N,the'pintle J being now vertical, while the other pintle, K, ishorizontal.

If it should be desired to use a swinging arm similar to the one seen inmy old patent, the socket of said arm can be applied to the pintle J, asindicated by the dotted lines 0, thereby leaving the lamp free to beturned around to the most convenient position; but if it should bedesired to use an ordinary bracket (indicated by the dotted lines P) thespindle of said bracket can be inserted in the vertical socket F. Insome cases, however, it maybe necessary to clamp or permanently attachthe bracket to a vertical support, as seen at B in Fig. 3, in whichevent said bracket is applied at the desired level and secured -'inplace. This attachment may be made either by the thumb-screw L or bymeans of wood-screws S S], passed through the holes D D of limb B.

Ihe spindle of bracket 1? can now be swung No. 92, 053; but I know of noinstance where H, perforated at I I, being employed to consuch socketshave been applied to a bracket nect the extension E and limbs B O, thelatter having a pair of pintles and two separate sets limb, G,having thescrew L engaged therewith, of holes to admit screws or similarfastenings. for the purpose herein described. I 5 3 I claim as myinvention- In testimony whereof I affix mysignaturein f'ltllle1combination, in a lamp-bracket clamp, presence of two witnesses. 0 t eimbs A 13 O the limb .A havin a vera *w tical pintle, J, a hrizontalpintle, Kfand an ROBERT E extension, E, which extension is pierced withWitnesses: w two diametrically-opposite sockets, F G, the H.
